A CQRIEORATION OE MULTIPLE-WRITING MACHINE.

Application filed July 8, 1912.- Serial No. 708,130.

To all whom it may concern:

Be it known that I, FRANK Amos JoHN- son, a citizen of the UnitedStates, and a resident of Dunel'len, in the county of Middlesex andState of New Jerse have invented certain new and usefu ImprovementsinMultipl e-lvriting Machines, of which the following is. specification.

My invention relates: to machines for simultaneously writing a pluralityof signatures and is designed especially for signing checks or similarinstruments where there are a large number of signatures to he affixed.

It belongs to that class of' machines referred to in which the pens ormarking, members are secured to a common pen-bar which has a universalmovement in a horizontal plane and where the pen pressure is given andmaintained hy the hand oft'he writer.

My present improvement relates to the means for mounting thepen-carrying frame.

In the following description reference is made to the accompanyingdrawings, in which:

Figure I is a plan; Fig; 2-is a left elevation; Fig; 3 is a frontsectional elevation on the line. XXI; Fig. is an enlarged detail oftheparts identified by the reference characters thereon; Figs. 5, 6 and'7 are alternative constructions referred to in the description.

The construction of the penscarrying frame is substantially identicalwith that shown in the application referred to and is in the form. of aparallelogram the sides of which are pivoted. The pen-bar constitutes.one side of the parallelogram and, in the present instance a tubular bar2' constitutes the other; The remaining two sides are formed hy a pairof links 3' which are forked at both ends toinclose; the pen-bar and theopposite side of said frame to which they are pivotal'ly secured". This:construc; tion gives a parallel ruler" movement. permits the pens 4-. tobe carried: in a longitudinal direction with relation to the penbar towhich they are secured by adjustable clamps 5". The links 3" are pivotedto the pen-bar hy conical pins 6 which enter corresponding' centers inhlocks which. are attached to" the pen-bar and the links are attached tothe side 2* by similar conical pins also marked 6 and posts 8. Theseposts are firmly lined in the side 2" and are of Specification, ofLetters Patent Fatenited awa it, 1913.

sufficientlength to give the necessary leverjage to secure the requiredrigidity to the iframe, so that when the front end of the pen-bar isdepressed by the pilot 9,. to which it is Secured by an arm 10, thepen-har will be evenly depressed at both ends.

i My present improvement differs from the construction shown in theapplication referred to in the means for mounting the jpen-carryingframe to secure a parallel relciprocating movement. Instead of attachingone side of the pen frame to or mounting it upon a carriage which hasmore or I less' s ring to it, I provide atraveling shaft fl wlich hasrigidly secured thereto a pair 'of' supporting rolls 12' (one ateachend);

These rol ls rest upon trackways which are a formed in front and rearhrackets 14 which fare secured to the bed plate 151 The shaft v is heldto parallel movement right and left by a pair'of' gears I6 which meshwith a fcorrespond ing pair of racks 17 which are secured, one to eachof the brackets 14 'the pitch diameter of the gears Being the same asthe diameter of the rolls 12. The side 2 of the pen frame is providedwith a pair of brackets" or arms- 18 which have jconi cal bearing pins19, by means of which the shaft If is axially pivoted between said 'themin the" side 2 a pair of collars Q' are' added as shown in Fig. 45 atthe point where the 'osts' are inserted. The arms 18 may be shaped asshown in Fig; 6' (marked 18*) which Brings the shaft 11 outside of thetubular side 2- of the pen frame.

Bymaking the forked ends of the links 3 fa little longer, to al'low forthelongitud-inal movement of the pen-bar, as shown in Fig. 5 (marked andby turning: the arms which connect the pen" frame to the travei 7 ingshaft (marked 18") tothe left, a portion of the pen frame is thrown tothe opposite side of the shaft 11 from the pen bar" and the weight ofthe pens and pen-bar is 'partially'haiancedon the shaft 11 as a fat:crum. I provide; however, a special balance for the pen-liar to*partially -or' completely support it, as individual writers may prefer;I10

which consists of a counterweight 20, which is attached to a telescopingrod 21the parts being held by a screw 22. This rod is secured to acollar 24 which is loose on the side 2 of the pen-frame and which isheld between a collar 28 and an arm 25 which are fixed to the side 2.The arm 25 has a toe 25 which supports the counterweight rod 21 when thepen frame is in writing position. This construction allows the pen frameto be thrown completely over on the centers 19, as the arm 25 will leavethe rod 21 and the counterweight 20 will rest on the bed 15. The objectof making the rod 21 so long is to enable a small weight to be effectivein balancing the pen frame without, at the same time, unduly increasingthe total weight that has to be carried; so there is no danger frommomentum of the parts when writing rapidly.

Instead of the counterweight 20, a construction very similar oridentical with that shown in the application referred to may be used.Such a construction is illustrated in Fig. 7 The side 2 has a loose arma. which carries in its free end a roll 6. This roll acts against theunder side of a trackway c which is attached to a post d which issecured to the bed 15. An arm 6 which is fixed to the side 2 of theframe is connected by a spring f to the arm a. The action of the springf in holding the roll 1) against its trackway c and wholly or partiallysupporting the weight of the pen-bar is obvious. The documents 26 whichare to be signed are represented in Figs. 2 and 3 as supported on aplaten 27 which rests on a shelf or table T, by the side of the bed andat the left of the same. The transverse movement of the writing frame islimited by pins 28 in the brackets 14 and the brackets 18 haveprojecting hubs 18 which travel under flanges 14: of the brackets 14.
